+There are three main types of eclipses: solar eclipses, lunar eclipses, and transits.
+
+- Solar Eclipses:
+  - Solar eclipses occur when the Moon passes between the Earth and the Sun, blocking all or part of the Sun's light.
+  - There are three types of solar eclipses:
+    - Total Solar Eclipse: The Moon completely covers the Sun, creating a brief period of darkness (totality) in the areas where it is visible.
+    - Partial Solar Eclipse: The Moon covers only part of the Sun's disk, resulting in a partial blocking of sunlight.
+    - Annular Solar Eclipse: When the Moon is farther from Earth in its orbit and appears smaller in the sky, it doesn't fully cover the Sun, leaving a ring of sunlight visible around the Moon.
+- Lunar Eclipses:
+  - Lunar eclipses occur when the Earth passes between the Sun and the Moon, causing the Earth's shadow to fall on the Moon.
+  - There are three types of lunar eclipses:
+    - Total Lunar Eclipse: The entire Moon passes through the Earth's umbral shadow, causing it to appear red or coppery during totality.
+    - Partial Lunar Eclipse: Only a portion of the Moon passes through the Earth's umbral shadow, resulting in a partial darkening of the lunar surface.
+    - Penumbral Lunar Eclipse: The Moon passes through the Earth's penumbral shadow, causing a subtle darkening of the lunar surface that is often difficult to observe.
+- Transits:
+  - Transits occur when a celestial body passes directly between an observer and another celestial object. The two most common transits visible from Earth are Mercury and Venus transits.
+  - Mercury Transit: Mercury passes between the Earth and the Sun, appearing as a small black dot moving across the Sun's disk.
+  - Venus Transit: Venus passes between the Earth and the Sun, also appearing as a small black dot crossing the Sun's surface.
+
+Each type of eclipse or transit offers unique astronomical phenomena and opportunities for observation and scientific study.
